This invention relates to connecting rod bearings for multiple cylinderengines, air compressors and the like, and my object "is to produce abearing susceptible ol use with engines in which the crank shalt remainsstationary while the Cylinders revolve around 'it, it being under-stoodhowever, that the bearing is also practicable for use in themore"conventional type ol engine in which the shaft revolves and thecylinders are stationary.

A further ob ect is to produce a connect;-

ing rod bearing for a multiple cylinder engine, which lies in theplaneoi the major axes or": all of the cylinders so that the thrust of thepistons shall be direct and without sidethrust. Another object is toprovide a narrow bearing for a series (it coimecting rods lying in thesame plane, in which the bearing elements of the'rods detachablyinterlock each-otherin position against lateral displacement.

A hearing rod connection otthc character above-outlined can be producedat relatively low cost, and makes provision fl er-maximum strength andminimum weight, in that the piston thrust of; the rods on the bearing isalways direct, and the cranl: case-dire relatively wide and heavy part01 the ordinary enginemay be materially reduced in width and weight.

lVith the objects set tlorth as desirable in view, the inventionconsists in certain novel and useful features of construction andcombinations of parts as hereinafter described and claimed; and in orderthat it may be fully understood reference is to be had to theaccompanying drawings, in which 1- Figure 1 is a side elevation of thebearing.

Figure 2 is a section on the line IIII oil Figure 1.

Figure 3 is a. section on the line IIIIII of Figure 1, but turned aroundso that its axis shall be parallel with the axis of the bearing as shownby Figure 2, for convenience in readability.

Figure 4:, is a section on the line IVIV oi? Figure 2. c

Figure 6 is an elevational view of the inner faces of the two bearingelements disclosed by Figure 5.

to be shrunk or otherwise rigidly mounted onthe crank shaft (not shown),of an engine, and said collaris preferably provided with a peripheralchannel 2, constituting a ball-race, two series 01 balls 3 in asuit-able skeleton cage at, occupying the ball-race at opposite sides ofand equal distances from its center.

As shown, there are four connecting rods, 5 and 6 for the pistons of twocylinders, and 7 and 8 for the pistons of the other pair of cylinders,the pistons and cylinders being omitted from the drawing, as having nodependent relation to the bearing.

The inner ends of the rods 5 and 6 terminate respectively in similarrings 9 and 10, abutting at their inner faces in the plane otthe axes ofthe rods, as shown clearly by Figure 2, said rings being internallychannelled at 11 to receive the cage and balls.

Ring 9has a pair of short peripheral arcuate flanges 12 and 13, and aninternal areaate groove 14 at the junction of the connecting rod 5 withsuch ring, the said :groove and flange 12 being disposed at right anglestoeach other, and the flange 13 at the opposite side of the axis of thering and about equally distant from flange 12 and the groove 1 i, asshown clearly by Figures 4 and 5.

The ring 10 has a short peripheral arouate flange 15 to engage groove14: (see Figures 2 and 5), an arcuate groove 16 at the junction 01 theconnecting rod 6 with the ring, for the reception of flange 12 (seeFigure 4), and an arcuate grooved peripheral lug 17 for the reception offlange 13. In assembling, the said rings are abetted together at theirinner faces with the rods at a lesser angle apart than a right angle sothat the various flanges, grooves and lugs are relatively offset, andthen the rings are rotated oppositely to cause the respective flanges12, 13 and 15 to enter the groove 16, the groove of lug 17 and thegroove 14, respectively. The two rings are thus interlocked together asregards lateral displacement, but are capable of relative rotary oroscillatory movement, it being understood that as they are fittedtogether they are also fitted on the ball-bearing.

The inner ends of the rods 7 and 8, respectively, terminate in rings 18and 19 of diameter fitting snugly over rings 10 and 9, respectively, andprovision is made for permitting the said rings 18 and 19 to abut attheir inner faces, by providing them with notches 20 in their inneredges, two of such notches 20 of rings 18 and 19, accommodating theconnecting rods 5 and 6, as shown by Figures 2, 3 and t, the saidnotches being of length to accommodate relative rotary or oscillatorymovements of the various rings. The rings 18 and 19 other than theirdifference in size and their formation with the notches 20, and thegrooves for the ball bearing, are in all respects similar to rings 9 and10, that is to say, each is provided with a peripheral flange 21engaging a groove 22 ot the other, corresponding to flanges 12 and 15and grooves 16 and 14- ot rings 9 and 10, and ring 19 has a peripheralgrooved lug Q3 and ring 18, a peripheral flange 24:, engaging the lug 23as in Figure 1.

In operation the rings turn on or with the ball bearing and. are alsotree to oscillate independently, the thrust from all of the connectingrods being toward the center of the bearing and always radially of itsaxis. The parts of the bearing can be eas ily and quickly assembled inoperative relation. The bearing is inexpensive and possesses thedesirable qualities of simplicity and durability, in addition to thosehereinbet'ore enumerated. It is also susceptible to modification withinthe spirit and scope of the appended claims.

I claim:

1. A bearing comprising a pair of inner rings and a pair of outer ringsarranged in telescopic relation, the rings of each pair having tongueand grooved connections to hold them against separating movement, and

rods respectively for and extending radial- 1y outward from said rings,the axis of all of the rods lying in the plane of the inner edges of therings.

2. A bearing comprising a pair of inner rings and a pair of outer ringsarranged in telescopic relation, the rings of each pair having tongueand grooved connections to hold them against separating moven'ient, androds respectively for and extending radially outward from said rings,the axis of all of the rods 1 in in the )lane of the inner cd 'es of therings, the outer pair o'l rings having notches accomn'iodating the rodsof the inner pair of rings.

3. A hearing comprising a collar having a ball-race, a ball bearingencircling the collar and engaging the ball-race thereof, a pair ofrings of equal diameter l'itting over the ball bearing and provided withinternal channels accommodating the ball bearing, means interlocking therings together as regards separable movement but leaving them free forii'ldependent rotation, connecting rods rigid with said ringsrespectively and extending radially therefrom, a pair of outer ringsfitting rotatably upon the inner rings and interlocked together regardslateral separating movement and relatively rotatable, and providedrespectively with radial connecting rots; said outer rings havingnotches in the inner edges through which the connecting rods of theinner rings extend radially outward.

In Witness whereof I hereunto atlix my signature,

JASON E. HARRIS.
